Wide Column, Large RAM-Type Vertical Turning Center at IMTS 2016, Booth S-9100
Doosan Machine Tools America, located in booth S-9100 at IMTS 2016, demonstrated its recently introduced series of large capacity, ram-type vertical turning centers. The series is comprised of the PUMA VTR1216 and the PUMA VTR1216M, which is equipped with an addtional spindle for milling, providing convenient, efficient mill-turn capabilities on one machine tool platform. Both machines offer a number of productivity enhancing features. The one-piece bed with dual chip conveyers greatly improves chip handling and reduces downtime for manual chip removal. Up to four tools can be mounted in quad holders that can be integrated into the tool magazines with capacities available from 12 to 34 stations, increasing the number of total tools for automatic selection and reducing the tool change time while improving productivity.
Main table speeds of 60 hp-400 rpm and live spindle speeds of 20 hp-3000 rpm (VTR1216M) offer the power and speeds needed to fully take advantage of today’s cutting tool technology.
According to Bob Baldizzi, Technical Sales Specialist for Doosan’s large machines, “IMTS attendees will want to see the new Pumas because they are the world’s first vertical turning centers with a turning tool indexing system. The system provides 90 degree indexing on turning tools, making it possible to mount four different turning tools on each holder. The result is significantly reduced average tool change times and increased tool capacity for resulting in shorter cycle times and fewer set-ups between operations.”
One of the main benefits of the single, wide column design is that it provides full X-axis travel distances allowing machining and probing on both sides of the workpiece and a 1,200 mm (47.2 in.) Z-axis travel. Both machines in the series provide a cutting capacity of 1,700 mm (67 in.) in diameter and 1,250 mm (49.2 in.) in height. The cutting envelope is 125% larger than its predecessor.
Both models are built to offer heavy roughing and accurate finishing. The VTR 1216 and VTR 1216M are designed and built with long service life in mind with 17,600lbs. (8,000 kgf) load capacity main tables, cross roller bearings, a curvic coupling tool holder interface providing 17,600 lbs. (8,000 kgf) of tool clamping force, a dual pinion C-axis (VTR1216M), and rigid construction design and materials.
